ACRP CCRP EXAM with complete updated
questions & answers
Transformation of Variables - answer the replacement of a variable by a
function of that variable: for example, replacing a variable x by the
square root of x or the logarithm of x. In a stronger sense, a
transformation is a replacement that changes the shape of a
distribution or relationship.
Parallel Design - answer Subjects are randomized to 2 or more tx groups
simultaneously
Crossover Design - answer Subjects are randomized to a sequence of
treatments (like Abbott) example: treatment A, then treatment B
Pre-Post Design - answer participants are measured on the dependent
variable before and after an intervention
Factorial Design - answer Two or more treatments are evaluated
simultaneously (varying combinations of treatments) to study
interaction effects
Type I Error - answer mistaken rejection of the null hypothesis
